We provided the mechanical and electrical engineering design for a new 1,500 ton chiller plant to replace the existing air conditioning system at the Kahului Airport. Our design included the replacement of the chiller plant components which included: three (3) 500-ton centrifugal chillers, three (3) chilled water and condenser water pumps, three (3) cooling towers, all necessary piping (chilled water piping within the chiller plants and condenser water piping between the plant and cooling towers), and all electrical switchgear and conductors in the MCC. In addition, we designed the central plant upgrade to conform to ASHRAE 15 standards and NFPA standards.
We also designed a direct digital control system that will control the chiller plant operations and maintenance and interface with the existing Johnson control central control system. The control system will not extend to the air distribution system and we also provided an inspection and evaluation of the existing air handlers for Buildings A and B and performed mechanical and electrical design to remediate the deficiencies found.
Total construction cost was $3,500,000.
